LIJDWIG MANTLER, OF ST. LOUIS, MISSOURI.

WRAPPER.

its. 926,270.

To all whom it may concern:

Be it known that I, LUDWIG MANTLER,-a citizen of the United States, residing at St. Louis, State of Missouri, have invented certain new and useful Improvements in Wrappers, of which the following is a full,

- clear, and exactdescription, reference being had to the accompanymgdrawings, forming a art hereof.

y invention has relation to improvements inpackage-wrappers; and it consists in the novel construction of wrapper more fully set forth in the specification and pointed out in the claims. V

In the drawings, Figure 1- is a plan'of the outer face of a blank from which the wrapper is formed; Fig. 2 is a face elevation of the wra per folded over four sides of a box or Y pac age, p rts'being broken'away; Fig. 3 is a erspe e of the box" with Wrap er parly folded against the ends of t e box; Fig. 4 is a perspective of the box showing one end of the wraptper partially sealed Fig. 5 is perspective 0 the box showing one end of the wrapper full sealed; and Fig. 6 is a del, tail section on the line 66 of Fig. 1;

,The object of my invention is to provide any conventional form of paper or other wrapper for boxes or packages containing food i'oducts such as flour, meal, cereals, and t me like, which are liable to be attacked by insects, or erms, or be materially affected by moisture w hich may set up fermentation,

.of equivalent chemical action within the body-of the material confined in the package,

with means which shall serve as an effectlve barrier against ingress of germs, insects,

' and other influences into the-body of the package, such barrier consisting in the pres-V. .ence at'the seams of the wrapper ofa suitable composition which is impervious to such germs andinsects, and notaffected to any material extent by moisture or changes of tem erature or variations in atmospheric con itions.

The composition here referred to is disposed on, the wrapper in close proximity to the usual adhesive with which the blank is provided and by which the seams of. the

wrapperfrom which the, package is constructed, are sealed.

The advantages of the invention will be i better app-grant from a detailed description thereof W 'ch is as follows:

Referrin to the drawings, and for the present to ig. 1 thereof, said figure repre- Specification of Letters Patent.

.sition Patented June 29, 1909.

sents a paper or other blank or sheet from which the wrapper is formed, the blank being foldable over any conventional form of sixsidcd box or package. The blank is'composed of sections 1, 2, 3, 4, 4, 5, and 6, each section covering its corresponding facerof the package about which the blSJIk'lS wrapped, the blank folding along the several dotted lines shown in the figure. The figure represents the outer face of the blank as wrapped about the package as will be clearly apparent by reference to the remaining figures of the drawings. Disposedalong the edges of the terminal sections 5, 6, are strips of adhesive or; lue a, a, a similar pair of adhesive strips or ayers a, a being disposed along the edge of one of the sections 4 (com lementary to section 4). These adhesive layers a, a in each case are spaced apart, the intervenin space being providedwith a composition superposed overa layer of paraffin or .wax c To the composition of the layer 12 either'alone or in conjunction with the bottom layerc, the virtue of my invention is attributable. The layer 1) is composed of resin mixed with sufficient oil or equivalent diluent or solvent to impart thereto the consistence of a paste or mucilage and is then spread on the reviously applied layer of paraffin 0. he layer a is merely to prevent the resin and oil mixture from penetrating the fiber of the paper, the paraffin being unaffected by the composition of the layer 6. The oil which'I prefer to mix with the resin is olive oil, though it is to be understood that I do not confine myself specifically thereto, since any suitable sects into the package, and while itself form ing a harmless compositiomyet at the same time it is germ-proof, insect-proof, to a deree water-proof, and not materially affected l )y changes in temperature. For temperate climates a lower percent of resin would be employed than in hot countries, the compoeing apt to flow in a hot climate if the percentage of oil were too great.

In practice, the blank as shown in Fig. 1 1s first turned over and one face of the packa e or box B is placed over section 1 of the blan this constitutes say, the bottom of the package. as finally wi'apped. The sections 2, 3

are then brought up against the sides of the 7 box,- and then the sections 4, 4 are brought in overlapped relation against the face opposite the section. 1 (Fig. 2) the section 4 being 5 lapped over the strips a, 6,0. of the comple- -Inentary section 4; and pasted thereto. It may be stated that the layer b adhere to the strip 4 as'well as the glue-strips or layers a, a, but of course the primary sealin is supposed to bedone by the glue, that of t e str p bbeing in a measure but secondary. In the next step of the operation the end sections 5, 6, opposite the overlapped complementary sections 4, 4 arefolded against the end of the box B, (Eig'." 3) leaving the composition layers a, b, a in position to be engaged by the ends of the overlapped sections 4, 4! which are accordingly folded down and cemented to the ends 5, 6 (Fig. 4) leavingtwo triangular projections which are finally glued down to the folded ends 4, 4 (Fig. 5) when the wra per is complete. Of course, in practice any d or form of wrapper will answer and the presj ent is only one example out of many. In all cases however, the resinous layer 7) must be so disposed along the glued seams that it will serve as a barrier to the ingress of insects, germs and the like. Glue and similar adhesives (a, a) do not have the property ofintercepting germs, and insects, but there is some thing about the composition of resin which has such a result. Since therefore no germs or insects can gain access to the interior of the wrapper they will be effectively barred from entering the ackage or box B and the contents of the atter may be kept fresh for a considerable length of time.

Having described my invention, what I claim is 1. Awrapper blank or sheet rovided with sealing means, and a suitab e germ-proof composition disposed on the same surface with the sealing means in conjunction with and in juxtaposition to, such sealing means.

2. A wrapper blank or sheet rovided withsuitable' adhesive for sealing t e same,

and a composition having a resin base disposed on the same surface with the adhesive 1n conjunction with and in juxtaposition to,

said adhesive.

wrapperfor ackages' composed ofa sheet having suitab e adhesive for sealin the same about the package, and provide "with a compound of resin'and fat Oll on the same surface with the adhesive in con'unction with and in juxtaposition to, sai adhesive. r

4. A wrapper blank or sheet rovided with suitable adhesive for sealingt e edges isp of the same, a layer of paraflin osed on the same surface contiguous to said adhesive, and a coating of a compound having a resin base spread upon the paraffin.

5. A wrap er blank or sheet having a pair of adhesive ands or strips disposed contiguous to its edges for sealing the same, and

a coating of resinous com ound disposed between the adhesive ban for the purpose set forth. r

p 6. A wrapper blank or sheet having a pair of adhesive bands or .strips dis osed contiguous to its ed es for sealing t e same, a

layer of paraffin posed between the adhesive bands and a coating of a compound of resin and a suitable diluent spread overthe er blank or sheet having a pair ture of resin and afat oil spread over the parafin. I I 8. A package wrapper formed of a sheet sealed at the edgealand rovided with germproof composition in clbse relation to the adhesive sealing said edges and on the same. surface therewith. v

9. A wrap er blankorsheet having a pair of adhesive ands or strips dis osed'contiguous to its edges for sealing t e same, a layer of paraifin hesivebands, and a plastic coatin -of resin. and olive oil spread over the para%n.

In testimony whereof I affix my signature, in presence of two witnesses. 1 i
